Common infections that occurs during pregnancy

Common infections that occurs during pregnancy: Vaginal infections, including yeast infections, are common during pregnancy and are usually not a cause for concern. Uterine infections may produce more complications, however.

Vaginal infections during pregnancy

Someone who is pregnant might be more vulnerable to certain infections and may develop more severe complications if the infections are left untreated. Anyone who has even a minor infection during pregnancy should talk to a doctor or midwife.

Typical vaginal infections during pregnancy include:

Vaginal yeast infections

Vaginal yeast infections are caused by a fungus called Candida. These infections tend to occur during pregnancy because of changes in the immune system, increased production of glycogen, and higher estrogen levels.

According to a 2015 report, about 20 percent of all women have Candida, which rises to 30 percent during pregnancy. It appears to be more common during the second and third trimesters.

The most common symptoms of a vaginal yeast infection include:

itchiness around the vagina or vulva

a thick, white, cottage cheese-like vaginal discharge

an odor of bread or beer coming from the vagina

pain or burning in or around the vagina

pain or burning during sexual intercourse

People can use prescription or over-the-counter medications to treat a vaginal yeast infection. However, anyone who is pregnant should not use these drugs without first talking to a doctor or midwife.

It is essential to get a diagnosis before beginning treatment as other infections, such as bacterial vaginosis and chlamydia, can be confused with yeast infections.

If BV is left untreated during pregnancy, it might cause preterm labor, premature birth, and lower birth weight babies.

Group B Streptococcus (GBS)

Group B streptococcus (GBS) is a group of bacteria that come and go in the body but often frequent the vagina and rectum. They do not typically cause symptoms or even an infection. However, women who have GBS in their bodies when they give birth may pass it to their babies.

Mothers who have GBS will pass it on to their babies in 1 to 2 percent of cases. Although uncommon, GBS in a newborn can be fatal.

Testing late in pregnancy can detect GBS, and is a standard part of most prenatal care.

Treatment with antibiotics through a needle in a vein (IV antibiotics) can significantly reduce the risk of a GBS infection passing to the baby.

Uterine infections during pregnancy

An infection in the uterus can be dangerous for a variety of reasons. The infection may affect the placenta, harm the developing baby, cause premature labor, or lead to birth abnormalities.

Uterine infections can also make labor more dangerous and difficult. Some individuals experience organ failure and other life-threatening complications.

Uterine infections often develop when bacteria from the vagina travels to the uterus, so an untreated vaginal infection is a risk factor for uterine infections. A person is more susceptible to uterine infections if their membranes rupture during an extended labor.

Treatment includes antibiotics and may require hospitalization. If a fever develops during labor, a doctor or midwife will monitor the fetus. If the symptoms are severe, the doctor may recommend a cesarean delivery.

Other Infections that may occur during pregnancy

Pregnancy causes many changes in the body, making people more susceptible to complications from many infections.

For example, hormone-related skin changes during pregnancy can cause conditions such as eczema or severely dry skin. If the skin cracks open and bleeds, a serious skin infection, such as cellulitis, can develop. A rare skin disorder called Sweet’s syndrome is also more common during pregnancy than at other times.

Some other infections that may be more serious during pregnancy include:

The increased risk of these infections during pregnancy is not well understood but may be due to hormone and other changes that alter the number of blood cells in the body. For example, late in pregnancy, T cells that help fight infection decrease in number.

Pregnancy also causes increased blood circulation and demands on the heart. These demands can also worsen complications. For example, if a pregnant person develops pneumonia from the flu, they may have more difficulty breathing because of the increased demands the fetus places on the heart and lungs.

Some medications that can effectively treat common infections may be less safe during pregnancy. So it is essential that pregnant people who have an infection talk to their doctor or midwife to weigh up the benefits and risks of various treatment options.

How does maternal infections affect the baby?

Numerous infections can affect the developing baby. However, it is difficult for doctors to tell whether and to what extent a fetus will be affected.

Infections can affect a developing baby in one of three ways:

Harmong the mother, making her body less able to nurture the baby or requiring the use of drugs that may harm a fetus.

They can directly harm the baby by causing changes that lead to birth abnormalities.

contagious diseases, such as hepatitis, syphilis, herpes, and HIV, which can infect the fetus

chlamydia, which can cause eye infections and pneumonia

gonorrhea, which can contaminate the amniotic fluid, cause preterm labor, and lead to eye infections and possible blindness

fifth disease, which can trigger a miscarriage or cause fetal anemia

group B streptococcus, which can cause severe complications in newborns, and in rare cases can be fatal

toxoplasmosis, which can cause birth abnormalities and intellectual disabilities

Listeria, which can cause miscarriage, stillbirth, and birth abnormalities

cytomegalovirus, which is often harmless but can also cause birth abnormalities and intellectual disabilities

Zika, which is usually mild, can cause pregnancy loss or birth abnormalities in an infant

Zika infection, which is a disease carried by mosquitoes, may cause birth abnormalities and increase the risk for stillbirths and miscarriages in those who have the virus. However, it is unclear why some fetuses are affected, and others are not.

Other infections may also harm a developing baby, depending on the overall health of the pregnant person, when the infection developed, and whether the person has received treatment.

Preventing infections

The Centers for Disease Control and Prevention (CDC) provide some strategies to reduce the risk of developing an infection during pregnancy, including:

avoiding travel to areas where Zika is prevalent, and using bug spray to prevent mosquito bites

using a condom and asking a partner to be tested for sexually transmitted infections (STIs)
